  2. 2. large area of deposition at the mouth of a river
  3. 4. the force behind most mass movements
  4. 5. built to block and prevent wind erosion
  5. 6. most common force affecting erosion
  6. 9. broken rock and organic material
  7. 11. removal by friction or scraping
  8. 12. the freezing and thawing and refreezing that breaks down rock
